2021-03-09tar: fix base-256 output.Elliott Hughes
A tar file created by toybox tar with values large enough to need base-256 rather than ASCII octal caused a tar reader to crash, and caused GNU tar to complain. I note from the docs at https://github.com/libarchive/libarchive/blob/master/libarchive/tar.5#L326 that they imply that only the top *bit* should be set to indicate this format, not the whole top byte, to give a 95-bit or 63-bit field. But I don't think we can hit that in practice? Bug: http://issuetracker.google.com/181683612
2021-02-28Tar should remove empty directories where it wants to put a non-directory.Rob Landley
2020-08-24tar: add -I (--use-compress-program) support.Elliott Hughes
This also changes the other compression options (such as -j) so that we pass no arguments for compression and just -d for decompression, which is what -I does to its filter and which appears sufficient. (I think I used -dc before just out of habit, since that's what I've been typing on the command line for decades.)

2020-08-19Patch out memory leak in tar.cChris Sarra
2020-06-23William Djupström reported tar --exclude wasn't working. Fix and add test.Rob Landley
(Also fix -v output going to stderr when it shouldn't.)

2020-06-08tar: fix extracting long file pathsWilliam Djupström
2020-03-23tar: implement --absolute-names.Elliott Hughes
Used by the Linux kernel build when copying kernel headers to kernel-headers.tar.gz. Bug: http://b/152244851
2020-03-18Fix WARN_ONLY (and the one caller feeding it in the field it was checking).Rob Landley
2020-03-13Fix various typos.Elliott Hughes
In case I'm not yet in the running for the most pedantic change of this release, I think the "days of the week are written with initial capitals in English" subset of this patch is a strong contender. (Found via `toybox help -a | ispell -l | sort | uniq`.)
2020-02-02Canonicalize the usage: lines for the POSIX toys.Elliott Hughes
This only touches 24 of the 68 toys/posix/ files --- the others were already canonical. Potentially contentious, so worth stating explicitly, is that there were 8 matches for "COMMAND..." amongst all existing help output, with 7 matches for various inconsistent variants involving something with "ARG", so I resolved that in favor of using "COMMAND..." (which is also shorter overall, and avoids nested []s).
2019-12-28Change variable type to avoid typecast.Rob Landley
2019-12-28tar: fix memory write errorEmmanuel Nicolet
Clear the last byte of the allocated buffer.
2019-11-13Pedantic constant annotations to shut up older toolchains.Rob Landley
2019-10-27Tar extract should delete files or symlinks where it's making a directory,Rob Landley
but --restrict checking should run on the path up to the last component before unlinking so tar can't be tricked into deleting random files off the system.
2019-10-04Fix extracting old tarballs, not just -tv of them.Rob Landley
2019-10-03Improve support for extracting older tarball formats.Rob Landley
2019-09-18Fix tar creation with hole at end.Rob Landley
The "gratuitous extra entry" is only gratuitous when there isn't a hole. (Which we can detect and not include but then we wouldn't match other implementations.)
2019-09-16bug: tar tvf blah.tar.xz was running xz when it meant xzcat.Rob Landley
2019-09-15Fix tar files that end sparse (need to call truncate), and display/exportRob Landley
length of sparse files properly.
2019-06-25tar: implement --mode.Elliott Hughes
Used by build/make/tools/mktarball.sh in AOSP. (Which is why today's switch to toybox tar got reverted.)
2019-06-01Teach file to recognize xz archives and old style tarballs.Rob Landley
2019-06-01Teach tar to extract older tarballs.Rob Landley
2019-05-25Toybox doesn't provide bzip2 or xz compression side (and the roadmap has it asRob Landley
out of scope), but the AOSP build airlock doesn't provide bzcat and friends. So tar needs to be able to use both: check for *zcat first, and fall back to "compressor -d" if it's not there.
2019-05-23tar: turns out --sparse is also known as -S.Elliott Hughes
Found trying to build the aosp_cf_x86_phone-userdebug target. The good news is that the targets that I knew were using tar with sparse files all pass now.
2019-05-20Less incomplete tar help text.Rob Landley
2019-05-19Fix tar sparse extract with extension blocks.Rob Landley
2019-05-19Fix tar --sparse generation of extension block.Rob Landley
2019-05-19Add pointless trailing --sparse entry for exact binary compartibility.Rob Landley
There's no possible use for this, but debian's tar produces it, so...
2019-05-19Add --sparse file creation support to tar.Rob Landley
And fix tar cv to produce output to stderr when archive going to stdout.
2019-05-14Checked in a debugging printf. Oops.Rob Landley
2019-05-14Typo caused a segfault. (Oops.)Rob Landley
2019-05-13Fix a couple error paths that don't continue archive create/extract properly.Rob Landley
2019-05-11Teach tar to extract type 'S' sparse file headers.Rob Landley
2019-05-01tar: use same tools for decompression as for compression.Elliott Hughes
This is what GNU tar does, so Android's build system jail allows bzip2, gzip, and xz, but not bzcat, zcat, and xzcat. Why the function? Because auto-detection works by setting toyflags, so we need to make sure we test the flags late, so it's either two copies of this or a function.
2019-04-21Promote tar.Rob Landley
There's probably more to do, but it seems usable at this point.
